Alzheimer cafè: toward bridging the gap between cure and care in patients with dementia.

BACKGROUND: Alzheimer's disease (AD) is the most common form of degenerative dementia, whose symptoms usually appear in the pre-senile age. In the early stages, patients present social difficulties due to the general cognitive decline in memory, language and executive domains. These problems also affect patients' quality of life, emotions, and mood, leading to social isolation. OBJECTIVE: The aim of this study is to evaluate the effects of Alzheimer's Cafè (AC) on the cognitive and behavioral outcomes of AD patients. METHODS: Twenty patients diagnosed with AD, who attended the Cognitive and Behavioral Rehabilitation Laboratory of the IRCCS Centro Neurolesi 'Bonino-Pulejo' of Messina, Italy, from December 2017 to December 2018, were enrolled in this study. As these patients belonged to the experimental group (EG: n = 20), they received specific cognitive-behavior training using the AC modality. The patients were assessed by a neuropsychological evaluation at the beginning and at the end of the program. Their outcomes were compared to a matched group of patients with neurodegenerative dementia (CG: 20) receiving conventional cognitive training. RESULTS: The pre-post comparisons showed that both CG and EG had a significant improvement in global cognitive functioning (MoCA p < 0.001) and in perceived quality of life (<0.001). However, only in the EG, we observed a significant increase in social functioning (SASS p < 0.00), the perception of mental well-being (SF-12 Mental p < 0.00), and a reduction in the depressive state (GDS p < 0.00). CONCLUSIONS: The present study suggests the importance of AC for patients with AD and the potential effect on psychological and social well-being.

Improvement of brain functional connectivity in autism spectrum disorder: an exploratory study on the potential use of virtual reality.

Patients with Autism Spectrum Disorder (ASD) need to be provided with behavioral, psychological, educational, or skill-building interventions as early as possible. Cognitive Behavior Therapy has proven useful to manage such problems. There is also growing evidence on the usefulness of Virtual Reality Therapy (VRT) in treating various functional deficits in ASD. This exploratory study is aimed at assessing the changes in cognitive functions in children with ASD, and the putative subtending neurophysiological mechanisms, following the provision of rehab training using an innovative VRT system. Twenty patients with ASD, aged 6-15 years, were provided with 24 sessions of VRT by using the pediatric module of the BTS NIRVANA System. Neuropsychological and EEG evaluations were carried out before and at the end of the training. After VRT, all patients showed a significant improvement in their cognitive-behavioral problems concerning attention processes, visuospatial cognition, and anxiety. These findings were paralleled by an evident reshape of frontoparietal connectivity in the alpha and theta frequency range. Our study suggests that VRT could be a useful and promising tool to improve ASD neurorehabilitation outcomes. This improvement is likely to occur through changes in frontoparietal network connectivity following VRT.

Parental involvement in robot-mediated intervention: a systematic review.

Introduction: Over the years, the conceptual approach to pediatric rehabilitation has reevaluated the parent's role in the therapeutic process, considering parental involvement as a necessary condition for the effectiveness of the intervention. In the field of pediatric intervention, the therapeutic use of robots represents a growing clinical interest, but the feasibility and applicability of these robotic interventions, including those involving parents, remain unclear. This systematic review aims to investigate parental involvement in robot-mediated interventions (RMI) for children and adolescents in the current literature. Our main goal is to analyze and summarize all existing studies to discuss and draw future research directions and implications for clinical practice. Method: After collecting results from 1,106 studies, the studies selected were analyzed using thematic analysis. The literature review was conducted in accordance with the PRISMA guidelines by searching databases such as PubMed and Web of Science until 07 February 2023. Studies that met the following inclusion criteria were included: (1) the use of a robot as a therapeutic-rehabilitation tool and (2) the presence/involvement of parents/caregivers in child-robot therapeutic sessions. Results: A total of 10 articles were included. The extracted data included study design, participant characteristics, type of robot used, outcome measures, aim, and type of intervention. The results reveal that parental involvement in RMI could be feasible and useful in improving intervention efficacy, particularly in improving the child's social-communicative abilities and the caregiver's educational skills. Discussion: RMI intervention with parental participation could be a useful therapeutic strategy in pediatrics. However, to date, few studies have investigated this specific topic, and the reported results may enhance future research to understand its effectiveness in specific areas of use.

Exploring the Usefulness of a Multi-Sensory Environment on Sensory Behaviors in Children with Autism Spectrum Disorder.

Background: Autism spectrum disorder (ASD) is a complex neurological development with social and communication deficits and sensory abnormalities. Sensory problems have a significant impact on daily life. Multisensory environments (MSEs), such as Snoezelen® rooms, offer controlled sensory stimulation. This study aims to evaluate the effect of MSE intervention with self-controlled sensory interactions on adaptive developmental skills and sensory responses in preschool ASD children. Methods: This pilot study was single-blind, randomized, controlled, and adhered to the CONSORT guidelines. Twenty participants were recruited and randomized into two groups: the control group (CG) underwent treatment as usual (TAU) with individual rehabilitation sessions of psychomotor therapy. The experimental group (EG) underwent TAU integrated with the use of an MSE. Developmental abilities and severity levels were assessed, pre-post, with the Psychoeducational Profile, Third Edition (PEP-3) and the Second Edition Childhood Autism Rating Scale (CARS-2). Results: A significant difference in taste, smell, and tactile behaviors according to the CARS-2, as well as in gross motor skills according to the PEP-3, was observed in the EG. Conclusions: This pilot study suggests that MSE-integrated intervention may be a valid strategy to improve self-management of the sensory profile in autistic individuals. Further studies are needed to better identify the intervention methodology and effectiveness.

Feasibility and Effectiveness of Speech Intervention Implemented with a Virtual Reality System in Children with Developmental Language Disorders: A Pilot Randomized Control Trial.

Language disorders are characterized by impairments in verbal expression/understanding, including difficulties with one or more language components. The Virtual Reality Rehabilitation System (VRRS) is a bioelectromedical device equipped with exercise sections aimed at improving cognitive and language deficits. It also increases patient motivation and engagement. The aim of our study was to test the feasibility and efficacy of VRRS intervention to improve speech therapy treatment for children with speech disorders. Thirty-two patients were enrolled in this study and randomly assigned to the experimental (EG) or control group (CG). The CG underwent conventional speech therapy, while EG underwent VRRS-implemented speech therapy. Both groups were evaluated before (T0) and after (T1) the intervention using the Language Assessment Test. The results showed improvements in both groups. However, the EG group showed greater improvement in various areas, including comprehension of total words, repetition, naming of body parts, naming of everyday objects, total naming, morphosyntactic accuracy, sentence construction, average length of utterance, and spontaneous word production. This study demonstrated that VRRS can be a valuable tool for implementing effective speech rehabilitation. Further studies are needed, as the use of VRRS is still in its early stages, requiring larger samples sizes and long-term follow-up.

Virtual Reality Technology to Enhance Conventional Rehabilitation Program: Results of a Single-Blind, Randomized, Controlled Pilot Study in Patients with Global Developmental Delay.

Global developmental delay (GDD) is a complex disorder that requires multimodal treatment involving different developmental skills. The objective of this single-blind, randomized, controlled pilot study is to evaluate the feasibility and effectiveness of conventional rehabilitation programs integrated with the BTs-Nirvana virtual reality system. Patients with GDD aged 12 to 66 months were enrolled and treated for a 48-session cycle. Patients were randomized into two groups, (1) conventional treatment and (2) conventional treatment supplemented with the use of BTs-Nirvana, in a 1:1 ratio. Before and after treatments, areas of global development were tested with the Griffiths-III Mental Developmental Scale and the clinical indicator of global improvement were measured with the Clinical Global Impressions-Improvement (CGI-I). Feasibility was confirmed by the high retention rate. The experimental group presented a significantly improvement in General Quotient (GQ) after treatment (GQ, p = 0.02), and the effect of the two treatments was significantly different in both the GQ (t =2.44; p = 0.02) and the Foundations of Learning subscale (t =3.66; p < 0.01). The overall improvement was also confirmed by the CGI-I (p = 0.03). According to these preliminary data, virtual reality can be considered a useful complementary tool to boost the effectiveness of conventional therapy in children with GDD.

Innovative use of virtual reality in autism spectrum disorder: A case-study.

Autism Spectrum Disorders (ASDs) are developmental disorders affecting communication and behavior. ASD incidence in the world population is about 1%, with a 4:1 ratio between males and females. In clinical practice, ASDs have been usually treated with cognitive-behavioral approaches, involving a face-to-face interaction with the therapist. Over the last years, virtual reality (VR) has played an important role in neurorehabilitation, even for ASD cognitive treatment. A 16-year-old boy with severe ASD and his caregiver were enrolled in the study. Two different cognitive trainings were administered; first, the boy was submitted to one-month cognitive behavioral therapy (CBT); then, after one month of rest, a combined approach using VR (by means of the BTS-Nirvana System) and CBT was applied. Only the combined approach provided an improvement in attention processes and spatial cognition skills, with a significant reduction of ideomotor stereotypes. According to this experience, the use of VR in addition to CBT could be a useful and promising tool to improve cognitive function in individuals severely affected by ASD.

Brain functional connectivity in chronic tic disorders and Gilles de la Tourette syndrome.

The pathophysiology of chronic tic disorder (cTD) and Gilles de la Tourette syndrome (GTS) is characterized by the dysfunction of both motor and non - motor cortico - striatal - thalamo - cortical (CSTC) circuitries, which leads to tic release and comorbids. A role of fronto - parietal network (FPN) connectivity breakdown has been postulated for tic pathogenesis, given that the FPN entertain connections with limbic, paralimbic, and CSTC networks. Our study was aimed at characterizing the FPN functional connectivity in cTD and GTS in order to assess the role of its deterioration in tic severity and the degree of comorbids. We recorded scalp EEG during resting state in patients with cTD and GTS. The eLORETA current source densities were analyzed, and the lagged phase synchronization (LPS) was calculated to estimate nonlinear functional connectivity between cortical areas. We found that the FPN functional connectivity in delta band was more detrimental in more severe GTS patients. Also, the sensorimotor functional connectivity in beta2 band was stronger in more severe cTD and GTS patients. FPN functional connectivity deterioration correlated with comorbids presence and severity in patients with GTS. Our data suggest that a FPN disconnection may contribute to the motoric symptomatology and comorbid severity in GTS, whereas sensorimotor disconnection may contribute to tic severity in cTD and GTS. Although preliminary, our study points out a differently disturbed brain connectivity between patients with cTD and GTS. This may serve as diagnostic marker and potentially interesting base to develop pharmacological and noninvasive neuromodulation trials aimed at reducing tic symptomatology.
